Figure 2 It is a schematic diagram of the cross-sectional structure of the light distribution structure. Figure 3 It is a schematic diagram of the light output of the light strip structure.
[0028] The light strip formed by the light strip structure can be realized without other profile structures, and has a self-contained light distribution structure 100 to focus most of the light within 45 degrees. At the same time, all the light within the range of 120 degrees to 180 degrees on the side is deflected to within 120 degrees, so as to achieve the effect of not seeing the light on the side.
[0029] In order to achieve the above-mentioned technical effect, the utility model provides a light strip structure, including: a light distribution structure 100 and a strip substrate 200, on which a strip LED lamp bead array 300 is arranged, and the light distribution structure 100 is arranged along the strip substrate 200 and covers the strip LED lamp bead array 300.
[0030] The light distribution structure 100 is used to adjust the light emitted by the strip-shaped LED lamp bead array 300. The light distribution structure 100 is a silicone material component. In order to make the light emitted by the strip-shaped LED lamp bead array 300 softer when passing through the light distribution structure 100, in some further specific embodiments, the silicone material component is a silicone material component with added diffusion material.
[0031] The light emitted by the strip-shaped LED lamp bead array 300 is configured at a specific angle through the light distribution structure 100. The structure of the light distribution structure 100 is designed so that its upper surface is a curved surface with a specific curvature. The curved surface has an overall outer contour in the form of an arc when viewed in cross section.
[0032] The outer contour includes a left arc and a right arc, and the left arc and the right arc are symmetrical with respect to the central optical axis 101 of the strip-shaped LED lamp bead array 300 .
[0033] From the cross-section, the light emitting point of the strip-shaped LED lamp bead array 300 is defined as the central light emitting point k, and the central light axis 101 passes through the central light emitting point k. In order to facilitate the description of the curvature variation structure of the outer contour, a rectangular coordinate system needs to be established.
[0034] In the present application, the central light-emitting point k is taken as the origin, the y-axis extends upward along the central light axis 101 , and the x-axis extends leftward along the horizontal line.
[0035] Since the left arc and the right arc are symmetrical based on the central optical axis 101. In the established rectangular coordinate system, the left arc and the right arc are symmetrical based on the y-axis. For ease of explanation, this application takes the left arc as an example. The left arc is composed of four arcs, and for the convenience of describing these four arcs. This application records the four arcs as the first arc A1, the second arc B1, the third arc C1 and the fourth arc D1. Among them, there are five nodes distributed on the left arc, which are the first node a, the second node b, the third node c, the fourth node d and the fifth node e. The arc between the first node a and the second node b is the first arc A1. The arc between the second node b and the third node c is the second arc B1. The arc between the third node c and the fourth node d is the third arc C1. The arc between the fourth node d and the fifth node e is the fourth arc D1.
[0036] In order to better describe the structures of the first arc A1, the second arc B1, the third arc C1 and the fourth arc D1, this specific embodiment describes the first arc A1, the second arc B1, the third arc C1 and the fourth arc D1 by establishing rectangular coordinates.
[0037] in,
[0038] The first arc A1 satisfies: .
[0039] The second arc B1 satisfies: .
[0040] The third arc C1 satisfies: .
[0041] The fourth arc D1 satisfies: .
[0042] Through the above mathematical formula, the curvature shapes of the first arc A1, the second arc B1, the third arc C1 and the fourth arc D1 can be restricted.
[0043] Different curvatures will cause different refraction effects, and since the arc on the left is symmetrical to the arc on the right. Therefore, the entire light distribution structure 100 will be divided into eight light distribution areas. Under the action of these eight light distribution areas, the strip LED lamp bead array 300 outputs the set light distribution effect through the light distribution structure 100. This light strip structure can deflect the light toward the side to the direction close to the vertical center axis of the light strip, and can focus most of the light within 45°. At the same time, all the light within the range of 120° to 180° on the side is deflected to within 120°, so as to achieve the effect of no light on the side.
[0044] The utility model sets a light distribution structure 100, and sets arcs of various curvatures on the light distribution structure 100, so that the entire light distribution structure 100 forms eight areas. Under the action of the eight light distribution areas, the strip-shaped LED lamp bead array 300 outputs the set light distribution effect through the light distribution structure 100. Therefore, when the light strip is used, light distribution can be completed without using additional profiles, thereby reducing the expenditure cost of consumers.
[0045] In order to realize the automated production of the light strip structure, in some further specific embodiments, the light distribution structure 100 is integrated with the strip substrate 200 through a co-extrusion process. In the co-extrusion process, the entire light distribution structure 100 is formed into an outer mold and an inner mold. The strip substrate 200 is arranged in the inner mold. Since the outer mold covers the inner mold, the light emitted by the strip LED lamp bead array 300 can be refracted by the outer mold to realize the light distribution function.
[0046] In some further specific embodiments, the fitting degree satisfied by the first arc A1 in the rectangular coordinate system meets the following condition: The fitting degree satisfied by the second arc B1 in the rectangular coordinate system meets the following conditions: The fitting degree satisfied by the third arc C1 in the rectangular coordinate system meets the following conditions: The fitting degree satisfied by the fourth arc D1 in the rectangular coordinate system meets the following conditions: .
[0047] In order to ensure the highest efficiency of the light emitted by the strip LED lamp bead array 300, in some further specific embodiments, for this waiting structure, the power per meter of the strip LED lamp bead array 300 satisfies greater than or equal to 4W and less than or equal to 10W. The light efficiency of the strip LED lamp bead array 300 is greater than 80lm / W.
[0048] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
